Answer: B and E
Step-by-step explanation:
X-5+5x-12=25
x+5x=25+5+12
6x=42
x=42/6
x=7
Answer:
-5w^9.
Step-by-step explanation:
These two terms are what we call, 'like terms'. This means that they are terms whose variables and exponents are the same. 14w^9- 19w^9 have the variable w^9 in common.
In these cases, all we do is use the coefficients (the number in front of the variable). Hence, 14w^9- 19w^9, quite literally turns into, 14-19. If we complete the sum, 14-19= -5. Put it all together, we have -5w^9.
Hope this helps!
You just add the lengths of RS and ST together. In your case RT= 24
Answer:
A = s²
Step-by-step explanation:
A = s² where s represents the side lengths
Since the side lengths of a square are always the same, you can use the formula A = s² for a square instead of using A=l(w)
